Skin pore imaging using spectral-domain optical coherence tomography: a case report

Area of Science:

• Dermatology
• Cosmetic Science
• Biomedical Imaging

Background:

• Sebum is a key skin component with implications in dermatology and cosmetics.
• Pore expansion caused by sebum can lead to various skin issues.
• Accurate analysis of sebum's morphological characteristics is necessary.

Purpose of the Study:

• To evaluate facial sebum areas using optical coherence tomography (OCT).
• To quantitatively determine pore size and analyze sebum morphology.
• To assess the effectiveness of OCT for skin analysis.

Main Methods:

• Utilized OCT to obtain maximum amplitude projection (MAP) and cross-sectional images of facial pores.
• Employed an ImageJ software algorithm for sebum detection within skin pores.
• Acquired images before and after sebum extraction to analyze pore size changes.

Main Results:

• Facial sebum areas were successfully evaluated using the OCT system.
• Quantitative analysis of pore size was achieved through OCT MAP images.
• Morphological characteristics of facial sebum were described using OCT.

Conclusions:

• OCT imaging provides a method for the morphological description of facial sebum.
• OCT enables specific analysis of skin parameters like pores and sebum.
• OCT-based skin analysis presents an effective approach for future research.
